DETAILED DESCRIPTION

[0020] The technical scheme of the present application will be described clearly and completely in combination with specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Embodiment: a sealing machine for paper towel packaging, like Figs. 1-3As shown, the system includes a frame 1, a U-shaped long plate 2 fixed to the frame 1, multiple horizontally spaced rollers 3 rotatably arranged in the middle of the U-shaped long plate 2, a U-shaped short plate 4 inverted and fixed to the U-shaped long plate 2, two parallel belts 53 transmission mechanisms 5 arranged on the top of the U-shaped short plate 4, a drive mechanism 1 6 that drives the two belts 53 transmission mechanisms 5 to run synchronously in opposite directions, a pair of heat clamps 7 movable inside the U-shaped short plate 4 and equipped with heating elements, and a drive mechanism 2 16 that drives the two heat clamps 7 to move closer or further apart. The gap between the two belts 53 transmission mechanisms 5 can clamp and pull. The opening of the tissue bag moves, and the direction of movement of the tissue bag is consistent with the conveying direction of the roller 3. The two hot clamps 7 are parallel to each other and slide in the direction away from or close to the gap between the two belts 53 transmission mechanism 5 respectively. The belt 53 transmission mechanism 5 includes a pair of rotating shafts 51 vertically rotatably set in the top of the U-shaped short plate 4, a pair of pulleys 52 respectively fixed on the two rotating shafts 51, and belts 53 sleeved and installed on the two pulleys 52. The two rotating shafts 51 are close to the two ends of the U-shaped short plate 4 respectively. The drive mechanism 6 drives one of the rotating shafts 51 in the two belt 53 transmission mechanisms 5 to rotate synchronously in opposite directions.

[0022] Furthermore, the drive mechanism 6 includes a pair of meshing gears 61 and a motor 62. The rotating shafts 51 in the two belt transmission mechanisms 5 rotate through the top wall of the U-shaped short plate 4 and are fixedly connected to the two gears 61. A protective box 41 is fixedly installed on the outer top of the U-shaped short plate 4, covering the two gears 61. The motor 62 is fixed to the top of the protective box 41, and the output end of the motor 62 rotates into the protective box 41 and connects to the top of a rotating shaft 51. By adopting the above-mentioned meshing transmission structure of the motor 62 and the two gears 61, the two rotating shafts 51 can be stably driven to rotate synchronously in opposite directions. Simultaneously, the protective box 41 can hide and protect the gears 61, ensuring the safe meshing transmission of the gears 61.

[0023] Furthermore, a pair of symmetrical L-shaped long plates 42 are fixedly installed on the inner top of the U-shaped short plate 4. The lower ends of the rotating shafts 51 in the two belt transmission mechanisms 53 are rotatably connected to the horizontal parts of the L-shaped long plates 42, and all rotating shafts 51 and belts 53 are located in the middle of the vertical parts of the two L-shaped long plates 42. The gap between the two belts 53 is located in the middle of the gap between the horizontal parts of the two L-shaped long plates 42. Multiple support rollers 43 are vertically rotatably installed on the horizontal part of the L-shaped long plate 42. The support rollers 43 are evenly distributed in the middle of the belts 53, and the sidewalls of the support rollers 43 are in close contact with the part of the belt 53 that clamps the opening of the tissue bag. By using the above-mentioned L-shaped long plates 42, not only can the two rotating shafts 51 be stably supported to rotate and move within the inner top of the U-shaped short plate 4, but also, in conjunction with the support rollers 43, the vertical parallel posture of the clamping parts of the two belts 53 can be maintained, thereby stably clamping and conveying the opening of the packaging bag.

[0024] Further, the U-shaped short plate 4 is provided with an observation window 44 on each side, which can be seen inside. This not only facilitates the observation of the internal sealing process by the staff, but also facilitates the adjustment of the height position of the hot clamp plate 7.

[0025] Further, it also includes two pairs of L-shaped connecting rods 8 fixedly connected to the opposite sides of the two hot clamp plates 7, height adjustment rods 9 fixed to the other end of the L-shaped connecting rods 8 and vertically penetrating the top wall of the U-shaped short plate 4, long strip holes 10 opened in the top wall of the U-shaped short plate 4 for the height adjustment rods 9 to penetrate and slide, a pair of L-shaped short plates 11 symmetrically arranged on the outer top of the U-shaped short plate 4, two pairs of connecting heads 12 fixed to the back of the vertical part of the L-shaped short plate 11, through holes 13 opened in the two pairs of connecting heads 12 for the four height adjustment rods 9 to penetrate, threaded holes 14 opened in the side wall of the connecting head 12 and vertically penetrating the through hole 13, locking screws 15 threadedly connected to the threaded holes 14 and locking the height position of the height adjustment rod 9, and a second driving mechanism 16 driving the two L-shaped short plates 11 to slide towards or away from each other. By adopting the above technical scheme, the height position of the hot clamp plate 7 inside the U-shaped short plate 4 can be adjusted outside the U-shaped short plate 4, and the second driving mechanism 16 can be reasonably matched to stably drive the two hot clamp plates 7 to slide towards or away from each other.

[0026] Further, the second driving mechanism 16 includes a moving plate 161 slidingly arranged on the top of the U-shaped short plate 4 above the horizontal part of the two L-shaped short plates 11, a gas cylinder 162 fixed to the top of the U-shaped short plate 4 with the piston rod head fixedly connected to the moving plate 161, two pairs of sliding columns 163 fixed to the horizontal part of the L-shaped short plate 11, and two pairs of long strip holes 164 opened in the top of the moving plate 161 for the two pairs of sliding columns 163 to penetrate and slide. The two pairs of long strip holes 164 are arranged in front and back, and each pair of long strip holes 164 is in a figure-eight shape on the moving plate 161.

[0027] When the two hot clamping plates 7 need to be driven to move close to or away from each other, the piston rod of the cylinder 162 is first extended or retracted, so that the moving plate 161 connected to the head of the piston rod moves relative to the top of the U-shaped short plate 4. Due to the two pairs of slide columns 163 on the two L-shaped short plates 11, which are respectively slid in the two pairs of long strip holes two 164 on the moving plate 161, and the two pairs of long strip holes two 164 are arranged in front and back and each pair is arranged in a spread shape on the moving plate 161, therefore, under the movement of the moving plate 161, the two pairs of slide columns 163 will respectively push the two L-shaped short plates 11 to move close to or away from each other. Because the two L-shaped short plates 11 are connected to the two hot clamping plates 7 through the connecting head 12, the height adjusting rod 9 and the connecting structure of the L-shaped short plate, the two hot clamping plates 7 will finally move close to or away from each other under the sliding of the L-shaped short plate 11, thereby achieving the effect of controlling the movement of the hot clamping plate 7 inside the U-shaped short plate 4 from the outside of the U-shaped short plate 4.

[0028] Further, a pair of vertical support plates 45 are fixedly arranged on the outer top of the U-shaped short plate 4, and a pair of parallel guide rods 46 are fixedly connected between the two support plates 45. The moving plate 161 is located between the two support plates 45, and a pair of sliding plates 161a are fixedly arranged on the moving plate 161 for the two guide rods 46 to slide through. The cylinder 162 is fixed on one side of one support plate 45 facing away from the other support plate 45, and the piston rod of the cylinder 162 slides through the support plate 45 and is fixedly connected to the side wall of one sliding plate 161a on the moving plate 161. By adopting the connecting structure of the support plate 45, the guide rod 46 and the sliding plate 161a, the moving plate 161 can be reasonably moved above the horizontal part of the two L-shaped short plates 11 and in the middle of the vertical part of the two L-shaped short plates 11, and the sliding stability of the moving plate 161 on the top of the U-shaped short plate 4 can be effectively guaranteed.

[0029] Further, a pair of handles 91 are fixedly connected to the top ends of the two pairs of height adjusting rods 9, and the two L-shaped short plates 11 are located between the two handles 91. A spring 92 is sleeved on the height adjusting rod 9, and the two ends of the spring 92 are fixedly connected to the handle 91 and the connecting head 12, respectively. By adopting the handle 91, the height adjusting rod 9 can be lifted or lowered by the staff, so as to adjust the height of the hot clamping plate 7. At the same time, the spring 92 on the height adjusting rod 9 can slow down the falling speed of the handle 91 when the staff lowers the height adjusting rod 9, thereby avoiding the handle 91 and the connecting head 12 from pinching the fingers of the staff.

[0030] Further, one end of the two hot clamps 7 is respectively fixedly connected with a guide plate 71, and the two guide plates 71 are in an eight-shaped form inside the U-shaped short plate 4. By using the guide plate 71, the bag opening of the packaging bag can be guided to smoothly enter the middle of the two hot clamps 7, so as to avoid the bag opening of the packaging bag being cut by the end of the hot clamp 7 or being unable to move forward.

[0031] Working principle of the embodiment:

[0032] When it is needed to seal the packaging bag, first, the packaging bag is placed on the roller 3 of the U-shaped long plate 2, then the bag opening is manually pinched and aligned to be inserted into the gap of the two belts 53, then the driving mechanism one 6 drives the two rotating shafts 51 to rotate in the same direction, then the pulleys 52 connected with the rotating shafts 51 are respectively rotated to drive the two belts 53 to move in the opposite direction synchronously, and the packaging bag is pulled into the inside of the inverted U-shaped short plate 4 by using this mode; after the bag opening of the packaging bag moves to the middle of the two hot clamps 7, the driving mechanism one 6 is stopped to work, so that the packaging bag stays at this position, at the same time, the driving mechanism two 16 drives the two hot clamps 7 to move close to each other and clamp the bag opening, thereby realizing the effect of automatically sealing the packaging bag; finally, after the sealing of the packaging bag is completed, the motor 62 continues to work, so that the two belts 53 continue to clamp and pull the bag opening of the packaging bag, so as to complete the packaging bag sealed to be sent out from the other end of the U-shaped short plate 4. Compared with the traditional manual sealing, the above-mentioned automatic sealing process of the packaging bag is not only fast and efficient, but also the feeding and discharging processes are not directly contacted with the hot clamps 7, so the safety is higher than that of the traditional manual sealing.
